Stuck at getPlaylistById

[marcguillemdev]

I am trying to get the Top 100 songs from each country by indicating the playlist ID like this:

public async void retrieve_playlist(uint id_playlist) { var dez = DeezerSession.CreateNew(); var po = await dez.Browse.GetPlaylistById(id_playlist); var tracks_po = po.GetTracks();

        for(int i = 0; i < tracks_po.Result.Count(); i++)
        {
            listBox2.Items.Add(tracks_po.Result.ElementAt(i).Title + " de " + tracks_po.Result.ElementAt(i).Artist.Name);
        }
    }

The invocation is this:

retrieve_playlist(716146082);

But the result is this:

System.NullReferenceException: 'Referencia a objeto no establecida como instancia de un objeto.'

Thanks in advance

According to the API explorer the playlist doesn't exist.

This library should be throwing an exception telling you this so I'll look into that! Your code should be handling exceptions or null returns which should mitigate this issue until I can get the exception throwing fixed.

Oops, you are right, that playlist doesn't exist. I tried with this and still don't work.

The json parsing code was missing a custom converter meaning that objects fetched by their ID wasn't working.

71 fixes this and will be released to Nuget shortly after I post this :)
